Modeling of 2.5 Gbps-intersatellite link (ISL) in inter-satellite optical wireless communication (IsOWC) system

A high‐speed long‐haul wavelength division multiplexing–based inter‐satellite optical wireless communication link using spectral‐efficient 2‐D orthogonal modulation scheme

“…Chaudhary et al have used six wavelength channels where each channel carries 20 Gbps of information using the conventional NRZ modulation scheme,whereas in our proposed link, we have incorporated novel hybrid 2‐D orthogonal modulation scheme where each wavelength channel carried 50 Gbps of PolSK information and 50 Gbps of DQPSK information simultaneously to increase the transmission rate per channel to 100 Gbps. The increase in the maximum link reach in our proposed work as compared to the work in Chaudhary et al can be attributed to the fact that the first transparent window (850 nm of operating wavelength) performs better in an IsOWC link as compared to the third transparent window (1550 nm of operating wavelength) . The authors in Chaudhary et al have used 1550 nm of operating wavelength, whereas our proposed link operates on 850 nm of wavelength.…”

“…The deployment of laser technology for communication purposes, specifically for space communication was first exploited in 1962. In the last five decades, individual researchers, government agencies, research institutes, and companies have achieved tremendous progress in the field of optical wireless communication for inter‐satellite links and deep‐space applications . In inter‐satellite optical wireless communication (IsOWC) links, the information is transmitted between two satellites separated by a certain distance in space, orbiting either in same or different orbits.…”

Challenges to Inter-Satellite Communication System: A Review

“…SM module can be used for achieving BER with improved SNR ratio while transmitting less power for 2.5 Gbps data over ISL link of 1000 Km at 1550 nm wavelength [17].…”

The Role and Challenges of Free-space Optical Systems

“…Many researchers have reported the development in FSO link for inter-satellite applications [42][43][44][45]. In a experiment [42], the authors has derived the probability density function of optical intensity in the receiver plane and proposed scintillation indexed for the identification of intensity fluctuation which are helpful in designing of intersatellite links.…”

“…In another experiment [43], the authors have investigated the channel capacity for inter-satellite optical links to realize the high speed communication and proposed an optimum input distribution by maximizing mutual information for inter-satellite optical communications in the presence of random pointing jitter. In another experiment [44], the authors have reported enhanced improvement in inter-satellite link by implementing the square root module with data transmission rate of 2.5 Gbps. In another experiment [45], the authors used the series of micro ring resonators and an add/drop filter to generate a large bandwidth signal as localized multi wavelength for inter-satellite communication.…”
